9mm suppressed SBR

[Six Shooter Steve]

I picked up a PSA 9mm billet reciever that takes Glock mags the other day and am looking into a SBR project. I'm looking for a little insight from others who have ran a 9mm SBR suppressed. I'm in the stage on planning and picking up parts for my upper and my question is how short of a barrel can you run before you need to run a booster on your suppressor? It's really not a problem because I have a booster, but I would rather run without if possible. Appreciate any insight.

Nielsen device? Not necessary on a fixed barrel.

Thanks! Wasn't sure on the AR platform if it would be a issue or not.

No, fixed barrel = NO booster. I run 4.5" barrel. I have an AAC Tirant 9 with fixed barrel spacer.

Thanks goodcat, I was looking into the 4-6" range myself.

KJQ is running four inch barrel on his mpx. I'll be running that when I get my stamps.

Sorry I'm late, I was shooting stuff that needed shooting.

And Rookie did it first, I just stole his great idea. His will be completely different though.

I'm running a CMMG 8.5" barreled upper on a CMMG lower. It has a Griffin Arms 3 lug adapter. I use my AAC Eco-9 can in it with a AAC 3 lug mount.

It's pretty quite with the 147 factory loads and down right fun with my 165gr hand loads.

You don't need a booster on a fixed barrel.

And mine will be better simply because I'll be biased! Of course, mine is pure garbage because I don't have my stamps yet! Have I mentioned that this sucks?

The waiting game begins! Subsonic is just too much fun through a suppressed 9 sbr.

I load 147's for my sub loads right now, but the 165's have peaked my interest and I have been wanting to get a box to load up and try out.

I also use them for USPSA in my S&W 627 revolver. I'm using 3.9 of titegroup and getting pretty good results.

I hadn't heard that. I thought the .gov was here to help.

They are.

They help take your money and help you wait. And wait. And wait. And wait.

I think you missed a few waits.
